We are having a situation where we are getting random "javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted]" failures. The situation occurs randomly, but when it does occur, we are always doing multiple JMS publishes within 1 XA transaction. For each message we do this: 1) Get the connection factory "java:JmsXA" 2) Create a connection from the factory 3) Create a non-transacted JMS session 4) Create a queue sender 5) Create an ObjectMessage 6) Set the Serializable into the ObjectMessage 7) Send the ObjectMessage with the sender 8) Close the sender / session / queue connection Does anyone see a problem with this? Thanks in advance. Cory. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124910#...
